The West Virginia University Gall Mite Research Program, a joint project of the Davis College of Agriculture and the Eberly College of Arts and Sciences, applies molecular and morphological approaches to evolutionary investigations of the Superfamily Eriophyoidea. We examine the Superfamily as a whole, but we have a particular interest in taxa of agricultural importance and in cryptic species. Additionally, we aim to share information with the wider scientific community through the establishment of a digital library and a training program for those interested in Eriophyoidea.

1. To infer systematic relationships in the mite Superfamily Eriophyoidea based on a broad sampling of taxa, i.e. all known genera. This analysis will be based on morphological and molecular data. Evidence of non-monophyly will be considered justification for revising the current system of classification.
2. Beyond seeking a taxonomic sample for the broader aim, we intend to include taxa that are likely to yield results of applied importance, and/or to reveal patterns of cryptic species.
3. To develop an electronic relational database, interactive illustrated keys, and a digital library, all to be accessible online.
4. To train new experts in eriophyoid taxonomy and identification.
